Question

Raju mixed salt,sugar,sand and oil in water.after sometime he could see only sand and oil.what could be the reason for it?​

Answer 1

Answer:

You are provided with a mixture of salt, sand, oil and water. Write the steps involved for the separation of salt, sand and oil from the mixture by giving an activity along with the diagram.

Answer 2

Answer:-

Because salt and sugar have dissolved in water and have occupied the spaces between the water molecules. But oil being lighter than water floats above it and sand being insoluble gets sedimented at the bottom of the container.
